ALK Technologies today announced that the North American version of its CoPilot Live GPS navigation system has been approved for sale on the iPhone App Store and is available immediately for iPhone 3G and 3Gs for a one-time fee of just $34.99. Detailed street maps of USA and Canada are stored on the phone - not downloaded each trip, so there's no need for extra hardware and no monthly fees.

Navigating to any destination is easy with CoPilot Live on an iPhone. Simply enter a house number, street or one of millions of pre-loaded points of Interest and it immediately works out the best route to get there.

On the road, iPhone users will enjoy sophisticated guidance features previously only found in expensive standalone or in-car systems. Turn-after-Turn display shows your next turn and the one after, while variable map zoom automatically adjusts the map display depending on your speed. CoPilot can also provide continuous guidance when you lose a GPS signal in a tunnel.

In addition to dependable guidance, CoPilot Live can use an iPhone's mobile Internet connection to bring additional real-time information to the driver. These 'Live' services include a 5-day weather forecast and a location-sharing feature called CoPilot LiveLink that allows users to check to location of friends on-screen or online. Real-time traffic information and gas prices will also be available shortly as an option.

CoPilot Live is available to buy immediately from iTunes App Store. Special offer pricing at launch is $34.99 for maps of USA and Canada. Pricing is for unlimited use, with no on-going fees or subscriptions.
